Jesus answered, “You do not know what you are asking. Are you able to drink the cup that I am to drink?” They said to him, “We are able.” (Matthew 20:22 ESV)
Have you ever met someone with an incredibly inflated idea of their capabilities? I know I have definitely been that guy from time to time. Sometimes assurance of what you can do is dangerous, but not always. Confidence can be great especially confidence that is grounded in Christ.
James and John were confident in their ability to follow Christ. Their mother was also confident. Probably too confident as she asked Jesus to seat her boys at his side in his kingdom.
How confident are you? How do you feel about your ability to follow Jesus? There are days when it certainly seems easier than others. There are days when it seems difficult. The truth is that Jesus helps us. Jesus gives us confidence. We need only receive it. In Jesus, we are able.
